Gigabyte Marvell OCP Type 25Gb/s 2-port LAN Card – PCI Express 3.0 x8 – 2 Port(s) – Optical Fiber – 25GBase-X – Plug-in Card

GIGABYTE 25GbE SFP28 LAN OCP Type Card

GIGABYTE’s CLNOQ42 dual-port LAN add on card features a Marvell FastLinQ 41202-A2G network controller
providing 25GbE Ethernet connectivity in a compact OCP Type 1 form factor card ideal to use with GIGABYTE’s server products that have an OCP mezzanine slot.

Marvell’s FastLinQ 41000 Series network controllers provide exceptional value in delivering industry-leading features and performance to enable the most efficient and agile software-defined data centers (SDDNs). Designed for the most demanding server and network virtualized environments
the 41000 series adapters enable Universal RDMA (RoCE and iWARP) as well as NPAR
VXLAN/NVGRE/GENEVE
and SR-IOV to boost server CPU efficiency and maximize application performance.

Overlay Networks Support (VXLAN / NVGRE / GENEVE / GRE)

In order to better scale their networks
data center operators often create overlay networks that carry traffic from individual virtual machines over logical tunnels in encapsulated formats such as NVGRE and VXLAN. While this solves network scalability issues
it hides the TCP packet from the hardware offloading engines
placing higher loads on the host CPU. The FastLinQ 41202-A2G controller on GIGABYTE’s CLNOQ42 effectively addresses this by providing advanced NVGRE
VXLAN
GENEVE and GRE hardware offloading engines that encapsulate and de-capsulate the overlay protocol headers
enabling the traditional offloads to be performed on the encapsulated traffic for these and other tunneling protocols (MPLS
QinQ
and so on).

RDMA over Converged Ethernet (RoCE) Support

GIGABYTE’s CLNOQ42 supports RoCE (RDMA over Converged Ethernet) and iWARP (Internet wide area RDMA Protocol) acceleration to deliver low latency
low CPU utilization and high performance on Windows
VMware
and Linux operating systems. FastLinQ 41000 Series controllers have the unique capability to deliver Universal RDMA that enables RoCE
RoCEv2
and iWARP. Marvell Universal RDMA provides the ultimate flexibility in accelerating use cases like Microsoft Storage Spaces Direct (S2D)
Windows Live Migration
VMware PVRDMA and vSAN
NVMe™ over Fabrics (NVMe-oF)
CEPHS and NFS over RDMA
and so on. And Marvell’s cutting edge offloading technology increases cluster efficiency and scalability to many thousands of nodes for hyper-converged infrastructure deployments. Customers looking to scale out NVMe-oF can leverage the FastLinQ 41000 Series capabilities of supporting NVMe-oF over TCP (NVMe/TCP) in addition to RDMA transports.

Hardware-Based I/O Virtualization Support

Designed for next-generation server virtualization: GIGABYTE’s CLNOQ42
featuring a Marvell FastLinQ 41202-A2G controller supports today’s most compelling set of powerful networking virtualization features: SR-IOV
NPAR
tunneling offloads (VXLAN
GRE
GENEVE
and NVGRE)
and industry-leading performance
thus enhancing the underlying server virtualization features.

• SR-IOV delivers higher performance and lower CPU use with increased virtual machine (VM) scalability.
• Marvell NPAR enables up to 16 physical
  switch-agnostic
  switch-independent NIC partitions per adapter. Dynamic and fine-grained bandwidth provisioning enables control of network traffic from VMs and hypervisor services.
• Concurrent support for SR-IOV and NPAR enables virtual environments with the choice and flexibility to create an agile virtual server platform.
• Availability of both RSS and TSS allows for more efficient load balancing across multiple CPU cores.
